Question

Собака увидела зайца на расстоянии 240 м, и помчалась за ним. Через какое время собака догонит зайца , если онапробигает в минуту 220М, а заяц 660?

Answer 1

Собака останется голодной

Answer 2

Собака не догонит зайца, т.к. разность их скоростей  660 - 220 =440м "в пользу" зайца

каждую минуту расстояние между ними увеличивается на 440 м

Answer 3

Calculation of Time for the Dog to Catch the Hare

To calculate the time it takes for the dog to catch the hare, we need to determine the relative speed between the two animals.

Given: - Distance between the dog and the hare: 240 meters - Speed of the dog: 220 meters per minute - Speed of the hare: 660 meters per minute

To find the relative speed, we subtract the speed of the hare from the speed of the dog:

Relative speed = Speed of the dog - Speed of the hare

Relative speed = 220 meters per minute - 660 meters per minute

Relative speed = -440 meters per minute

Since the relative speed is negative, it means that the hare is moving away from the dog. In this case, the dog will not be able to catch the hare.

Therefore, the dog will not catch the hare.
